Updated packaging scripts for Mac OS X
After thorough considerations and long discussions, we finally decided to included phonon with the bundled Mac OS X client...
Partial reorganization of Mac OS bundeling script.
Fix replacing Horizontal Tab with the unicode char

Commit 4676ff82af669595edaf090c97a28161d67782a1 caused horizontal tabs
to be replaced with the HT character of the unicode control char block.
Fix that by replacing it with 8 spaces again.
Only show warning about QCA on user input.

When compiled with QCA support, merely trying to decrypt messages
should not warn about missing qca-ossl; this message should only be
shown on user input (such as the key-related commands) and incoming
messages really requiring qca-ossl to function (key exchange).
Show a message when failing to load the key file

People got confused when quassel did not accept their keyfile; now a
message is shown hinting at the possibility of a passphrase being
present.
Never use the expressions "allows to", "helps to", "requires to" etc. Each of these expressions requires a direct object.

Update INSTALL info on LINGUAS.

Since 2573fe44 the buildsystem no longer uses a seperate option for LINGUAS, but rather uses the environment variable of the same name.
types.h: add missing include
Remove stray whitespace in INSTALL and README.
Strip formatting when looking up the clickable.

In the TopicWidget the list of Clickables is initialized with text
stripped of formatting, so when looking up their positions again, the
formatting should be stripped as well.

Fixes #1115
Don't respond to key exchange requests in channels
Properly detect CBC in key negotiation.

When FiSH starts a key exchange, it appends CBC to the key to indicate
that it wants to use CBC rather than EBC. The cipher code simply
rejected this key.
Remove unused cipher map.

Since the refactoring in 3146ad this map is unused.
Prepend the mode of operation to showkey's output.
Do not allow keyx to be used on channels.

Given that incoming exchanges are ignored for channels, it makes no
sense to send them either.
Indicate whether a key is set for the buffer.

This adds a lock icon on the right of the input widget when a key is
set for the current buffer. Encryption was isolated within CoreIrcUser
and CoreIrcChannel, so a new property on IrcUser and IrcChannel is
necessary to sync the current status.
Remove CoreBasicHandler::displayMsg without type.

Incomprehensible code, which actually caused a segfault in most of the
few places it was used. The only useful part is calling typeByTarget,
but that can be done in the calling site just as well.
